Biennial Chard produces fine-textured Spinach like leaves with much smaller stems than other chards. It will not go to seed in hot weather and will supply a steady source from spring until fall.
Seed outdoors as soon as weather and soil conditions permit. Sow seed 2 cm (1 in) deep, 5 to 6 seeds per 30 cm (1 ft) of row, in rows 45 to 60 cm (15 to 18 in) apart. Later thin plants to 15 cm (6 in) apart. Cultivate shallowly all season to avoid damaging the shallow roots. Seed outdoors as soon as weather and soil conditions permit. Successive seeding every 10 to 14 days will provide fresh chard all summer long. Swiss Chard may also be planted in the flower garden as a contrast plant.
